My 2000 Nissan Maxima SE is stocked with the 3.0L VQ30DE V6 engine. Heres all the information about the engine you could possibly like to know from wikipedia.org.
VQ30DEVQ30DEThe 3.0 L (2987 cc) VQ30DE has a bore and stroke of 93 mm and 73.3 mm respectively with a compression ratio of 10.0:1. It produces 193 PS (142 kW; 190 hp) to 230 PS (170 kW; 230 hp) @ 6400 rpm and 205 to 217 ft·lbf (278 to 294 N·m) @4400 rpm. The VQ30DE was on the Ward's 10 Best Engines list from 1995 through 2001. It is an aluminum open deck block design with microfinished internals and a relatively light weight.
An improved version of the VQ30DE is known by the designation VQ30DE-K. The K designation stands for the Japanese word kaizen which translates to "improvement". The engine was used in the 2000-2001 Nissan Maxima and adds a true dual-runner intake manifold for better high-end performance compared to some earlier Japanese and Middle-East market versions of this engine. The VQ30DEK produces 226 PS (166 kW; 223 hp). The 1995-1999 US spec VQ30DE was equipped with only a single runner intake manifold.
It will fit if the 2000 engine is a 3.0 L VQ30DE-K. They are almost identical engines
